JACK LYNCH TUNNEL: Traffic problems to be solved by end of 2022, when flyover will open

Construction of Dunkettle Flyover to begin this year, and be completed by end of 2022

Site Clearance Works are now underway at the Dunkettle Interchange Site. The below photograph shows the ongoing Works in the area north of the existing N25 – the large building in the background is the former IBIS Hotel. The Site Clearance Works will continue until March 2018 and clearance of the site will be followed by Archaeological Investigations throughout the site area.

Engineers expect that these Archaeological Works will take 3-4 months to complete. Detailed Survey Works will also continue over the coming period – basically, these works are on scrub land so there are no lane closures or significant traffic management measures.

The purpose of the various Advance Work items is to prepare the Works area to the greatest extent possible for the Main Works Contractor. The Main Construction Works Contract is currently out to tender and the roads authority hopes to appoint a Contractor over the coming months. Contractor appointment will be followed by a detailed planning phase but Engineers expect offline works to get underway before the end of 2018. A four-year Contract period is currently envisaged suggesting an overall completion date before the end of 2022.

N40 Works
Duct Installation Works are continuing along the N40 route as part of the National Broadband Strategy. These Works will continue for a number of months with Duct Installation Works also required on the N8 route from Dunkettle to Tivoli Overpass. No daytime lane closures are required on either the N40 or the N8 in the short term – details of any significant traffic management measures proposed will be circulated in advance in the normal way as we go along.
